Some Results on Cross Viewpoint Consistency Checking

The ODP multiple viewpoints model prompts the very challenging issue of cross viewpoint consistency. This paper considers definitions of consistency arising from the RM-ODP and relates these in a mathematical framework for consistency checking. We place existing FDTs, in particular LOTOS, into this framework. Then we consider the prospects for viewpoint translation. Our conclusions centre on the relationship between the different definitions of consistency and on the requirements for realistic consistency checking.
